Patent CA-1319490-C (CA)
Inventor: SAHARI HARRI
IPC: B22C7/02
Filed: 1988-12-07
Granted: 1993-06-29
Abstract: Abstract of the Disclosure The invention concerns a method for the preparation of moulds and cores used in the casting of metals.  In the method the moulds and cores are prepared out of a granular moulding material as well as out of a binder agent that binds the moulding-material granules together. The binder agent used for the moulding mix is an anorganic salt soluble in water and having a high melting point, as a rule higher than the casting temperature, which said salt is mixed with the granular moulding material as binder-agent solution dissolved in water.  In the moulding process the binder agent is crystal-lized out of its water solution physically so that the binder agent forms a solid bridge between the granules of moulding material, said bridge binding the granules of moulding material together.  The combination formed by the binder agent and the moulding material is chosen so that the binder agent and the main minerals of the moulding material are chemically unreactive with each other at the moulding and casting temperatures.

Abstract: DEFLECTOR RING FOR USE WITH INFLATORS   FOR PASSIVE RESTRAINT DEVICES                           ABSTRACT     A vehicle passive restraint device comprising an air bag positioned between an occupant of the vehicle and an interior portion thereof for protecting the occupant from an impact with the interior portion in the event of a collision involving the vehicle; a generator for producing a sufficient quantity of a gaseous combustion product to inflate the air bag means in an interval occurring between the collision and the impact in order to prevent the impact; and a deflector ring positioned between the air bag and the generator for attaching the bag to the generator and extending a sufficient distance into an interior portion of the air bag for preventing hot combustion gases and particulates produced within the generator from impinging directly against an inner surface of the bag.  The deflector ring is stamped from a relatively light weight material utilizing conventional stamping equipment without the necessity of subjecting the ring to any machining treatment.  The ring possesses sufficient structural strength to position and maintain the air bag in relation to the generator when the generator is actuated in order to inflate the air bag.

Title: Regulator valve for an ink marking system
Inventor: DICK GEORGE H
IPC: F04C14/00
Filed: 1989-03-29
Granted: 1993-04-20
Abstract: ABSTRACT OF THE DISCLOSURE          A unitary pump, regulator valve/pulsation dampener, and interconnecting passageways is provided.  The regulator valve/pulsation dampener includes a flexible member disposed in a chamber arranged between the fluid input and fluid output. The diaphragm flexes as a function of the pressure in the chamber to control the opening and closing of a bypass valve member and, in addition, damps out both high and low frequency pulsations generated in the ink by the pump.  When the pressure in the system increases beyond a predetermined limit the valve member is opened to divert some of the fluid flow into a bypass passageway until the pressure falls below the predetermined limit.  The pressure limit in the system can be varied by adjusting the external pressure applied to the flexible member using an adjustment screw and compression spring.

Abstract: ABSTRACT OF THE DISCLOSURE         A millimeter wave imaging system is disclosed which has wide applicability throughout transportation and related industries.  For example, the system may be used to provide an aircraft pilot with an image of a landing field which is essentially unaffected by fog, rain, snow, blowing sand, etc. The system comprises an array 36 of imaging elements 66 as its fundamental component.  Each of the imaging elements 66 of the basic array 36 comprises an antenna consisting of a pair of conductive elements 68 and a non-linear circuit element 80 connected thereacross.  The paired conductive elements 68 are designed so as to detect millimeter wave radiation emitted by or reflected from objects in the field of view, and the non-linear circuit elements 80 rectify the millimeter wave energy thus detected, providing an output corresponding to the millimeter wave energy received.  The imaging elements are disposed in the focal plane of a lens or mirror 40.  Each of the elements 66 of the array 36 may provide the signal for one or more pixels of an image signal, such that a focal plane imaging array is thus provided.  A image can then be formed responsive to millimeter-wave radiation without complex processing steps or any form of mechanical or electronic scanning.         To increase the sensitivity of the imaging array system, a local oscillator signal 26 may be mixed with the energy 12 received from the field of view in each of the imaging elements by the non-linear circuit element.  The oscillator 26 used to provide the local oscillator signal can also be used to illuminate the field of view.  Coded beacons 1 emitting encoded millimeter wave energy for detection by the imaging array may also be employed.  Preferred constructions of the imaging array and of suitable millimeter wave sources are disclosed, as are a number of applications for this technology.

Abstract: ABSTRACT OF THE DISCLOSURE    A multiplex signal processing apparatus in a signal transmitting and receiving system includes at the transmitting side: a first amplitude-modulator for modulating a first carrier by a main signal to obtain a vestigial sideband, amplitude-modulated main signal; a second amplitude-modulator foe modulating a second carrier which has the same frequency but differs in phase by 90° from the first carrier by a multiplex signal to obtain a double sideband, amplitude-modulated multiplex signal; an inverse Nyquist filter for filtering this signal to obtain a vestigial sideband; amplitude-modulated multiplex signal; and in adder for adding the vestigial sideband, amplitude-modulated main and multiplex signals to obtain a multiplexed signal. The apparatus at the receiving side includes: a Nyquist filter for filtering the multiplexed signal; a carrier regenerator for regenerating the first and second carriers from the multiplexed signal; a main signal detector for detecting the main signal from the multiplexed signal passed through the Nyquist filter by suing the first carrier; a filter for removing quadrature distortion from the multiplexed signal; and a multiplex signal detector for detecting the multiplex signal from the multiplexed signal passed through the filter by using the second carrier. By inverse Nyquist filtering the auxiliary signal in quadrature to the picture carrier, a normal synchronous receiver will produce a conventional television signal without distortion (crosstalk) caused by quadrature distortion of an auxiliary signal containing additional picture information while at the same time allowing relatively simple demodulation of the auxiliary signal in improved receivers without adding distortion.
